Iranian officials have arrested six people accused of teaching Zumba dancing and trying to "change lifestyles", media reports say.

The group of four men and two women were charged over their dancing and not adhering to the hijab dress code.

Instructors allegedly "attracted boys and girls, taught them Western dances", and posted videos to social media.

The Latin American fitness routine has proved controversial in Iran, which has laws restricting dance.

"The members of a network teaching and filming Western dances have been identified and arrested," Hamid Damghani, a commander of Iran's Islamic Revolutionary Guard Corps, was quoted as saying by local media outlets.

"They were arrested by the Guards' intelligence forces while teaching and creating video clips... as they sought to change lifestyles and promote a lack of hijab," he said.

Hijab rules govern the wearing of headscarves and clothing in public places by women, and dancing with the opposite sex is banned, except in front of immediate family members.
